" i-Claims, (Cl. 132-43) This invention relates to a hair curling endwrap for curling or setting human hair and simultaneously. treating thehuman hair'with' a compound which isa member oftljie B complex vitaminsessential for growth and norm al "maintenance of the hair,which;compound per se is extremely diificult to apply to the hairprimarily because ofits highly viscousfistate and to the method forvmaking such a hair curling end wrap. More specifically, this inventionrelates toa ha1r.curlmg end wrap for curling or setting human hairandsimultaneously' treating the human hair and scalp with'a d(+)- 7alpha,gamma-dihydroxy beta,beta-dimethyl. butyric-acid-"(hydroxy-alkyD-amide," more particularly, d(+.)-alpha,

'garrima-dihydroxy- N (3 hydroxypropyl)-beta,beta-dimethylbutyramide ord( +)-pantothenyl alcohol .or dfPanthenol and to the method for makingsucha hair curling end wrap.

D( +)-pantothenyl alcohol is a-viscous, slightly hygroscopic liquid andonly the dextrorotatory form has. vitamin activity and is prepared bythe addition of propanolamine to optically activealpha,gamma-dihydroxy-beta,

beta-dimethylbutyrolactone, as disclosed in U'.S.*- Patent i No. 2,413,017,} and has the formula D(;|-)-pantothenyl alcohol or d-Panthenol,because of its :hig hly viscous state, has been difficult to handleparticupantothenyl; alcohol or d-Panthenol is soluble both in watenian'din awater-soluble-aliphatic alcohol of -low 1 molecular, weight, such asmethylalcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, -ormixtures of these alcohols.

fAs heretofore stated, it is known that d-Panthenol has been employedtopicallyfor various derrriatoses' in a cream or ointment in the amountof about 2%. to about 5% by weight'of-the cream or ointment, andsuchcreams are, by their very nature, .greasy andrather difficult to applyto the hair. Further, the amount of d-Panthenol in the cream or.ointment is extremelysmall withrespect to the amount of the,otheringredients therein and any application of same necessarily involves theapplication of the other cream or ointment ingredients together-with thed-Panthenol to the area to which said cream or ointment is applied.Therefore, the application of such a cream or ointment to human hairnecessarily involves also the application of very large amounts of othergreasy ingredients, which have no direct beneficial effect to the hair,together with very small amounts of d-Panthenol to the hair and it isquite evident that the d-Panthenol will not be applied uniformly to thehair so treated.

D-Panthenol, by its very nature, viz. its high viscosity, possessesgreat utility as a grooming agent for human hair in addition to itsvalue as a B complex vitamin essential for both growth and normalmaintenance of human hair and the scalp. D-Panthenol has the consistencyof thick maple syrup. However, because of its highly vis- 3,087,501Patented; Apr. 30, 1963 orsetting end wrap for easily curling and.grooming human hair-and simultaneously-treating the scalp, said. endwrap comprisinga porous fabricuniformly impregnated with a .d(-alpha,gamma-dihydroxy-beta,beta-dimethylbutyric-acid-(hydroXy-alkyl-amide..

Still another object of my inventionis to providemeth- Other'objects of.my invention.willsbecome..readily apparent from the followingdescription which merely illustrates my invention and does-not limit myinvention.

I havediscoveredthat d(-|-)-.pantothenyl alcohol, .or d-Panthenohpersecan be very easily and .uniformly and a rapidly applied to human hairwhile simultaneously imparting-a curl or other desired shape to thehuman hair without utilizing in combination therewith any carrier. ma- 1ents such ashydrocarbons, a1cohols,.cream or ointment terials-such ascream-making orointment-making ingredibases, or the like which have nodirect beneficial effect to the hair and scalpwhen gusedin relativelylarge quantitles. This is accomplished with-a hair curling or settingend wrap comprising aporous fabric. such ashighly absorbenttporous paperof substantially high puritycellulose q paper hav-ing-a highwet-strength or cloth impregnated,

by -absorption and-adsorption, each with aneven, level,

uniform aplication of d-Panthenol. The fabric is'sufiiciently porousthat it can 'beuniformly impregnated with d-Panthenol by absorption andadsorption utilizing a solution of d-Panthenol in any of theaforementioned watersoluble'aliphatic alcohols having a low molecularweight. The porous fabric has athicknesspreferablyno greater than 0.020inch andpossesses sufiicient flexibility to enable strands or a;tuft-ortress of hair when embraced by the impregnatedend wrap to be rolled into-the-desired curl or'shape: The porous fabric preferably has a wetstrength 45 suflieientto withstand a tension of 50; grams applied to aone-half inchwide strip.

in using theend wrap of my invention, the hair is first thoroughlywetted with water--and then combed-into strands or tresses. Anendwrap-uniformly impregnated with d Panthenol is thenfolded around awet strandor tress of hair as closely to thescalp as possible and thenmoved towards the end of thestrand'or tress tocover the end of thestrand or tress and, by means of a roller, the water-wetted strand ortress in the so-foldd fabric-is 55 woundin the formof a rolled curl,using the roller as the form, and held in positionb-y fasteners such ashairpins or clips." The d-Panthenol being'soluble in water is uniformlyremoved from the-end wrap by the solvent action of" the water ontothehair of the strand or tress thereby uniformly grooming and treating thehair. The hair is allowed to dry, and the fabric together with theroller and fasteners are removed leaving a uniformly shaped curl eachhair of which is uniformly treated and groomed with d-Panthenol.

The hair curling or seeting end wrap of my invention is preferablyformed by thoroughly dissolving a predetermined amount of d-Panthenol ina predetermined amount of a water-soluble aliphatic, said respectiveamounts depending upon the type of fabric to be impregnated, alcohol oflow molecular weight such as methyl alcohol, ethyl alcohol, propylalcohol, isopropyl alcohol, or a mixture of at least any two of saidalcohols, substantially water free, thoroughly wetting the porousfabric, preferably the aforedescribed highly adsorbent high wet-strengthporous paper known as Goody curl tissue #129 which is the product of H.Goodman & Sons, Division of Delamere Co., Inc, of New York, New York,with said alcoholic solution, as by dipping or immersion, rolling on,etc'., and thoroughly drying said so-wetted fabric to remove thoroughlyfrom said so-wetted fabric the alcohol Solvent, thereby to obtain asubstantially dry d-Panthenol uniformly impregnated, by absorption andadsorption, end Wrap. As is quite readily apparent, the strength of thealcoholic solution with respect to the d-Panthenol varies with the typeof fabric used and the greater the ability of the fabric used to absorband adsorb d-Panthenol and still remain substantially dry, the greaterthe concentration of the dP.anthenol in the alcoholic solution. Like-Wise, the amount of d-Panthenol in the end wrap will vary with the typeof fabric used. Likewise, another consideration with respect to thestrength of the alcoholic d- Panthenol solution is of course governed bythe d- Panthenol alcoholic solution easiest to handle for impregnatingthe various fabrics. I have found most preferable with respect to theaf'oredescribed high wet strength paper having a thickness of 0.015 incha 2% d-Pan-thenol, by weight, alcoholic solution, the alcohol being awatersoluble aliphatic alcohol of low molecular weight, as hereinbeforedescribed. The end warp of my invention is uniformly impregnated withd-Panthenol and is substantially dry and does not adhere to a similar-1yimpregnated porous fabric when placed in contact therewith, as in thepackaging of same for sale thereof. Further, to hasten the drying of theaforementioned thoroughly wetted fabric, the so-wetted fabric may besqueezed, as by passing between rollers, to remove excess solution priorto exposure to the drying atmosphere.

The following examples for preparing the hair curling or setting endwrap of my invention are set forth for the purpose of illustration onlyand are not considered to be limiting.

Example 1 There are dissolved in 98 grams of substantially waterfreeisopropyl alcohol 2 grams of d-Panthenol and there is thusly formed a 2%d-Panthenol, by weight, substantially water-free isopropyl alcoholsolution. A sheet 9" x 8 /2" of high wet-strength porous paper, asheretofore described and known as Goody curl tissue #129, having athickness of 0.015 inch is immensed in said solution and thoroughlywetted with said solution. The sowetted paper is then dried, and theso-dried paper uniformly impregnated with d-Panthenol is notdistinguishable by the naked eye from untreated paper and is dry to thetouch. The impregnated sheet is cut into twelve 3" x 2" sheets and usedto curl or set and treat the hair on the human head in the mannerhereinbefore described. The hair is first wetted thoroughly with Waterand then combed into strands, twelve in number, to accommodate each 3" x2" d-Panthenol impregnated sheet. Each end wrap is folded around a wetcombed out strand of hair as closely to the scalp as possible and thenmoved towards the end of the strand to cover the strand end and, bymeans of a roller, the water-wetted strand in the sofolded fabric iswound in the form of a rolled curl, using the roller as the form, andheld in position by clips. D-Panthenol is thusly uniformly removed fromthe end wrap by the solvent action of the Water onto the hair of thestrand. The hair is allowed to dry, and then the papers together withthe rollers and clips are removed leaving twelve uniformly shaped curlseach hair of which is uniformly treated and groomed with d-Panthenol.

Example 2 There are dissolved in a mixture of grams of substantiallywater-free isopropyl alcohol and 8 grams of substantially water-freeethyl alcohol 2 grams of d- Panthenol and there is thusly formed a 2%d-Panthenol, by weight, substantially free alcoholic solution. Likewise,as in Example 1, twelve 3" x 2" end wraps are formed, each uniformlyimpregnated with d-Panthenol, and each is applied to human hair to formtwelve uniformly shaped curls each hair of which is uniformly treatedand groomed with d-Panthenol.

As is readily apparent, I have discovered an end wrap by means of whichhuman hair can be easily and uniformly curled or set, groomed andtreated with d(+)-pantothenyl alcohol or d-Panthenol, which prior to myinvention necessitated the use in combination therewith of ingredientshaving no direct beneficial effect on the human hair and was extremelydifiicult to handle because of its extremely viscous state.

Many changes and alterations may be made without departing from thespirit and scope of this invention which is set forth in the appendedclaims which are to be construed as broadly as possible in view of theprior art.
